- SDL_QuitSubSystem — Shut down a subsystem
- SDL_Quit — Shut down SDL
- SDL_WasInit — Check which subsystems are initialized
Before SDL can be used in a program it must be initialized with SDL_Init. SDL_Init initializes all the subsystems that the user requests (video, audio, joystick, timers and/or cdrom). Once SDL is initialized with SDL_Init subsystems can be shut down and initialized as needed using SDL_InitSubSystem and SDL_QuitSubSystem.
SDL must also be shut down before the program exits to make sure it cleans up correctly. Calling SDL_Quit shuts down all subsystems and frees any resources allocated to SDL.
